In fact, said NASA heliophysicist Lika Guhathakurta, it's true that the sun is currently in an active phase of its cycle, meaning electromagnetic energy has picked up. Large solar flares can impact electronics and navigation systems on Earth, but satellites monitoring the sun give plenty of warning and allow officials to compensate for the extra electromagnetic activity when it hits our atmosphere. What's more, Guhathakurta said, this particular solar maximum is the "wimpiest" in some time — scientists have no reason to expect solar storms beyond what our planet has weathered in the past.
